My grandmother was tricked by her son to give the house documents when her husband died. Now the same son has taken a loan of 500000INR which has now become repayment amount of approximately 1100000INR towards interest. In the meantime my grandmother has done gift deed to her another son(dead) some 4-5 years back and his son received a notice from the bank regarding the repayment and the case is held in court now.

Is there anything my grandmother can do to take the documents back and enforce her former son the forcefully pay the bank amount and he is refusing to do the same.
